How many pennies would be in a tower that is 10 miles
high?

Answers

Answer 1
Just measure the width (or height, if you'll be stacking the pennies
a mile high) of a penny, then divide 5280 feet by whatever you find.
This is a great activity for a class, and in fact a good way to start
the project. First take one penny, and work out an answer. Then get
100 pennies, and measure them; do the same calculation to see how many
pennies it will take to make a mile. There will probably be a
difference, because you can measure 100 pennies more accurately than a
single penny. Or maybe you have a micrometer that will measure one
penny precisely. Which is better can be a good discussion starter. And
don't forget to try it in metric, too.

Just to illustrate, using a very rough estimate of a penny's width,
let's say a penny is about 3/4 inch wide. The number of pennies in a
mile will be

5280 ft 12 in 1 penny
1 mile * ------- * ----- * ------- = 5280 * 12 * 4/3 pennies
1 mi 1 ft 3/4 in

This gives about 84,480 pennies. (This method of doing calculations
with units is very helpful, and would be worth teaching.)

If we measure 100 pennies as 6 ft 1 in, we will get

5280 ft 100 pennies
1 mile * ------- * ----------- = 5280 * 100 * 12 / 73 pennies
1 mi 6 1/12 ft

This gives us 86794.5205 pennies in a mile.

If each interior angle of a regular polygon is 144 degrees. Find the number of sides in it.

Answers

Answer:

10

Step-by-step explanation:

In a polygon

interior angle + interior angle = 180°, thus

exterior angle = 180° - 144° = 36°

The sum of the exterior angles in a polygon = 360°, thus

number of sides = [tex]\frac{360}{36}[/tex] = 10

Answer:

10 sides

Step-by-step explanation:

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440°.

Solve 12 + 12a + 4a = -4

Answers

Answer:

a=-1

Step-by-step explanation:

we need to get a by itself

first combine like terms

12+16a=-4

now we need to get rid of the 12 so subtract it to other side

-16=16a

now divide 16 by -16 which gives you -1=a

Answer: a=-1

12+12a+4a=-4

(Collect like terms)
12+16a=-4

(Move constant to the right-hand side and change it’s sign)
16a=-4-12

(Calculate the difference)
16a=-16

(Divide both sides of the equation by 16)
a=-1

[tex]Flat = \$5[/tex]

[tex]Additional = \$3/lb[/tex]

Required

What pound do both charges are the same

Represent the charges with x;

For UPS, it can be written as:

[tex]Charges = 7 +2x[/tex]

For FedEx:

It is:

[tex]Charges = 5 + 3x[/tex]

Equate these charges together

[tex]5 + 3x = 7 + 2x[/tex]

Given point (-6, -2) and a slope of 5, write an equation in slope-intercept form.

Answers

Answer:

y = 5x + 28

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 6, - 2) into the partial equation

- 2 = - 30 + c ⇒ c = - 2 + 30 = 28

y = 5x + 28 ← equation of line
